•
When relocating the equipment, first disconnect the telecom connection before disconnecting the power
connection. When the unit is installed in the new location, reconnect the power first, and then reconnect
the telecom connection.
•
The plug of power supply cordset is used as the main disconnect device. Ensure that the AC outlet is
located near the equipment and is easily accessible.
•
Slots and openings in the front, back and bottom of the cabinet are provided for ventilation; to protect it
from overheating, these openings must not be blocked or covered. The openings should never be blocked
by placing the product on a bed, sofa, rug, or other similar surface while in use. The product should never
be placed near or over a radiator or other heat source. This product should not be placed in a sealed
environment unless proper ventilation is provided.
•
Make sure that the surface behind the PBX is not made of wood.
•
When this product is no longer in use, make sure to detach it from the rack.
•
Use only the AC power cord included with the PBX. A certified power supply cord has to be used with this
equipment. The relevant national installation and/or equipment regulations shall be considered. A certified
power supply cord not lighter than ordinary polyvinyl chloride flexible cord according to IEC 60227
(designation H05VV-F 3G 0.75 mm²) shall be used.
•
When the PBX is mounted on a 19-inch rack, make sure that the installation of the unit does not cause the
temperature of the rack to exceed its limit.
•
Before opening the top cover, the AC power cord must be removed from the AC inlet.
•
For safety reasons, close the top cover and tighten the screws before operating the PBX.
•
If the PBX is not installed properly using the securing correct methods, the PBX may fall causing serious
damage.

Performing surge protection is essential. Make sure to follow the instructions in "4.2.10 Surge Protector
Installation".
•
It is strongly recommended to use TLS encrypted communication when the PC is accessing the PBX via
the Internet. To use TLS encryption, routers must have a port set up for https communication.
•
Avoid using the same AC outlet for computers and other office equipment, as noise generated by such
equipment may hamper system performance or interrupt the system.
•
Unplug the system from its power source when wiring, and plug the system back in only after all wiring is
completed.
•
CO lines should be installed with surge protectors. For details, refer to "4.2.10 Surge Protector
Installation".

When installing or removing the optional service cards, the power switch must be turned off.
•
For grounding wire, green-and-yellow insulation is required, and the cross-sectional area of the conductor
must be more than 0.75 mm
•
When connecting a PRI23 card to the CO line, connect through an NT1; do not connect to the U interface
of the CO line directly.
